vTEMPORARY BINDER.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application led August 22, 1905. Serial No. 275,264.

To @ZZ when@ it may concern,.-

Beit known that I, FRED B. JORDAN, a citi- Zen of the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to temporary binders embodying a pair of cooperating clamping members or jaws, and has for its objects to produce a comparatively simple inexpensive device of this character in which the jaws will be firmly and securely locked relatively in clamping position and one in which the locking members will be maintained in secure frictional engagement with the binderposts and one wherein the locking actuating member or head may be readily manipulated for releasing the parts.

Other objects of the invention are to provide a device of this character in which the length of the binder-posts may be varied at will and one wherein the locking members will when freed move automatically to releasing position.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is an end view of a binder embodying the invention and showing the clamping-jaws connected in action. Fig. 2 is a side elevation of the same viewed in the direction of the arrow in Fig. 1. Fig. 3 is a plan view looking in the direction of the arrow in Fig. 2 and showing the jaws partly separated. Fig. 4 is a horizontal longitudinal section taken on the line 4 4 of Fig. 2. Fig. 5 is a cross-section taken on the line 5 5 of Fig. 4. Fig. 6 is a perspective view of one of the locking members. Fig. 7 is a detail view of the cam-operating bolt or arbor.

Referring to the drawings, it will be seen that the improved binder comprises a pair of cooperating relatively movable clamping members or jaws 1 and 2, of which the jaw 1 has its normally inner face countersunk for the reception of a metal plate or strip 3, secured in place by means of screws 4 and provided adjacent its ends with the tubular portions or sections 5 of a pair of spaced binder elements or posts 6, situated, respectively, adjacent the opposite ends of the jaw 1 and adapted to project through suitable openings 7 formed in the jaw 2, the tubular sections 5, which are preferably formed integral with the plate 3, being internally screw-threaded at their outer ends, as at 8, for the reception of externallythreaded reduced portions or necks 9, provided on complementary post-sections 10.

The jaw 2 is provided at its inner and outer faces with longitudinally-extending channels or recesses 11, communicating at their inner ends with a central rectangular opening or slot 12, which receives the inner opposed ends of a pair of longitudinally-movable locking members or bolts 13, each comprising a pair of spaced side portions or arms 14, disposed, respectively, in the slots 11 and provided at their outer ends with substantially V-shaped seats or recesses 15, which receive the adjacent post 6 and'pre'sent engaging portions or fingers 16, adapted for frictional engagement therewith, the members 13 being terminated at their inner ends in reversely-inclined bearing or cam faces 17 and in substantially semicircular recesses 18 for a purpose which will presently appear, there being arranged within each of the members and having bearing at one end on an abutment 19 therein an eX- pansible spring 20, seated at its other end in a socket 21, formed in the jaw 2, these springs serving to automatically move the jaws to retracted or non-locking position.

Applied to the outer face of jaw 2 is a metal plate 22, retained in place by screws 23 and provided with acentral bearing-opening24, in which is arranged for rotation actuating bolt or arbor 25, provided at the inner face of the plate with a circular bearing-shoulder 26 and at the outer face of the plate with a knurled head 27, there being tapped onto the screwthreaded shank of the bolt a cam-head 28, having inclined bearing-faces 29, adapted to act respectively` on the bearing-faces 1T for moving the locking-bolts 13 to engaging position, it being understood that by rotating the actuating-bolt 25 in the proper direction for drawing the head 28 inward between the inclined faces of the bolts 13 the latter will be moved relatively outward against the action of the springs 2O and that under a reverse rotation of the bolt 25 the springs will act for moving the locking-bolts relatively forward.

The binder-post sections 10 are provided at their outer ends with internally-threaded sockets 30 to receive the reduced threaded portions 31 of knurled heads 32, applied as IOO IIO

an ornamental finish for the terminals of the posts, it being understood that under this arrangement the lengths of the posts may be varied at will by employing greater or lesser I number of the complementary sections which are provided at their outer ends with kerfs 32 for engagement by a screw-driver or other suitable tool for screwing the sections together.

In practice the jaws 1 and 2 are assembled in active relation by entering the posts 6 through the openings 7, the bolt 25 having' been previously manipulated for moving the head 28 outward from between the bolts 13 to permit their movement under the influence of springs 2O to non-engaging position. The binder is now adapted to receive the loose leaves 33, which are of course perforated, as usual, for engagement with the posts 6 and are entered between the clamping-jaws 1 and 2, which may, by releasing the jaw 2 in the manner explained, be moved relatively by seourely clamping the leaves and fixed in clamping position by manipulating the bolt 25 to draw the head 28 between the beveled ends of the locking members 13, thus forcing the latter relatively downward and causing the engaging lingers 16 to bite into and securely engage the posts 6. It is to be noted that under my improved construction and by providing the improved locking-bolts disclosed herein a screw engagement with the posts 6 is insured, thus to positively obviate relative movement of the jaws l and 2 when locked in clamping position.

From the foregoing it is apparent that I produce a simple inexpensive Jform of binder in which the locking-bolts present a maximum number or' contact-points for frictional engagement with the posts 6, and one in which the jaws will consequently be eifectually locked against relative'movement. it being understood that in attaining these ends minor changes in the details herein setforth may be resorted to without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a device of the class described, a clamping member, a pair of binder-posts carried thereby, a second clamping member having openings to receive said posts and provided with opposite longitudinal recesses communieating with an intermediate opening, a pair of locking members having spaced arms disposed respectively in said recesses and adapted for locking engagement with the posts, an actuating member disposed in the intermediate opening and having 'a head movable between the adjacent ends of the locking members for moving the latter to locking position, and springs arranged to act on the locking members Jfor automatically moving them to releasing position.

' In testimony whereof I aflix my signaturein presenceof two witnesses.
